One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream.

一个寒冷的夜晚，当我和几个学生在落基山脉徒步旅行时，我提到我们将要渡过一条山间小溪。

Was the little stream able to cross the desert at first?

起初这条小溪能穿过沙漠吗？

youdao

Or is she an elfish spirit, who, as the legends of our childhood taught us, is forbidden to cross a running stream?

要不，说不定她是个小精灵，象我们儿时的童话所教的，她是不准渡过流淌的溪流的吧？

youdao

The road will cross a small stream and continue parallel to the stream for some time before the first blue cross appears on the side barrier of a small cement bridge.
